Abstract

Tests of discrete symmetry violation have played an important role in understand the structure of weak interactions in the Standard Model of particle physics. Historically these measurements have been extensively performed at experiments with large samples of K and B mesons. A high luminosity tau-charm facility presents physicists with the opportunity to comprehensively explore discrete symmetry violation and test the Standard Model using tau leptons, charm mesons and charmed baryons. This paper discusses several possible measurements for a future tau-charm factory.
